The technique used by this artist to define form in this caricature's face is: * a. Cross-contour
b. Scribbling
c. Cross Hatching
d. Stippling

C. Cross Hatching

Explanation:

If you look on the darker part of the face, you can see crisscross lines that define shadows. they don't show form entirely but define shadows and highlights.

Hope this helps!

personally, i think the games do because it's actually them controlling it. this might cause them to think it's okay to do it for real. as for animated movies i think they are mostly fine because they're animated. also, animation has come a long way causing animated movies to become more real but 30 years ago this wouldn't be as big of a problem as today.
